IMPROVEMENT IN WIND-WHEELS.

Specification forming part of Letters Patent No. 50,705, dated October 31, 1865.

To all whom it may concern.-

Be it known that I, A. M. HANSEN, of Stockton, in the county of San Joaquin and State of California, haveinvented a new and useful Improvementin Self-Itegulatin g Vind-Mills; and I do hereby declare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to the annexed drawings, makin g a part of this specification, in Which- Figure l is a perspective View of the windmill; Fig. 2, viewofvaneB halfopen; Fig. 3, View ot' vane B open or in linewith the wind; Fig. 4, side View of vaneR open and attached to B; Fig. 5, View ofvane B closed or shut.

Letter A represents the wheel-arm B, band holding all the vanes B in a like position; C, spring attached to G witha rod or chain D, arm of B; E, screw-rod on which (l is regulated; F, wheel-shaft; G, guide fastened to I. Said G is earn-shaped, guiding the connecting rod or chain. H, tale for turning the wheel toward the wind; I, crank or arm fastened toB K, wooden rim; L, iron band surrounding K; M, turning-table; N, franie O,footboard 5 T, pivot; Q, braces; R, vane having three pivots, two -fastened on one edge, one at each end on which R is turning to or from, the third pivot fastened to It on the other corner, at the inside end, next to the center of the wheel, connected to B in where it is held.

The spring C, connecting to G, I, and B, holding the vanes R toward the wind, when the wind increases the vane Bopens or turns from the wind. The connecting rod or chain I is admitted by G nearer to the center of vane R, turning point, thereby snbduing the increased stiffness of C, being the same when vane B. is open or closed.

Operation: The wind acting on the valles B, causing the Wheel to revolve, when the wind increases the vane R opens, and can only resists the wind with the power C is regulated for; therefore the mill -wheel can receive no more driving force or run any faster.

NVhat I claim as my improvement, and desire to secure by Letters Patent, is-

The combination and arrangement of G, C', and R, for the purpose as herein described.
